Indirect Estimation of CH4 from Livestock Feeds through TOCs Evaluation
Feed, Fermentation Methane Total Organic Carbons
2016/5/9
Thirty-five available feeds were fermented in vitro in order to investigate their soluble total organic carbon (TOCs) and methane (CH4) production rate. A fermentation reactor was designed to capture ...
Reducing CH4 Emissions from Grazing Ruminants in New Zealand: Challenges and Opportunities
Methane Rumen Feed Monensin Fumarate Vaccination Breeding
2016/5/6
Almost half of New Zealand’s greenhouse gas emissions arise from agriculture and enteric methane (CH4) emissions arising from ruminant animals constitute 30% of total CO2-e emissions. Enteric CH4 emis...
内蒙古羊草草原不同物候期CH4通量日变化特征与日通量比较
2007/8/24
利用静态暗箱法对内蒙古半干旱羊草草原不同物候期原状群落与土壤CH4通量的日变化进行了野外定位试验研究，结果表明：羊草草原土壤为大气CH4的吸收汇，不同观测日CH4通量的日变化特征存在较大差异；气温及表层地温与CH4吸收通量除果后营养期呈显著或极显著正相关外，其余观测日两者的相关性不明显；原状群落与土壤CH4吸收通量间除2002年果后营养期以及2003年开花期两者差异分别达到...
